Is CoolStart safe?

Low risk

CoolStart loads third-party stylesheets and fonts whenever it opens its replacement new tab page.

CoolStart replaces the browser's new tab page and requests remote CSS and font resources as that page loads. Those requests go to cdnjs, Google Fonts, and Google's static font host, which can receive request metadata such as the user's IP address and referrer.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
